Open Hardware/Modding: Raspberry Pi, Arduboy, and More

Sean Hodgins’ holographic Christmas tree
Apparently we’re all calling persistence-of-vision projects holograms these days. Thanks ABBA.

The Raspberry Pi 5 Won’t Launch Any Time Soon
This news is disappointing but unsurprising. As explained by Upton, nobody wants to be on a waiting list for a Raspberry Pi. A new Pi computer would take up space on the manufacturing floor—it would slow the recovery effort.

My Festive Proof of Concept
So I knew that I needed to prove, if only to myself, that this was possible. But I also wanted to have some fun doing it. I decided that a good way to try to prove that a propeller could be spun without physical contact to the motor itself would be to make a snow globe that required no shaking, no touching. Just wave a hand in front of it, and excite the snow within. The motor and electronics would be hidden in the base, and the propeller, inside the globe, would excite the water and snow. Even with your hands full of gingerbread men and egg nog, you could still enjoy the magic of the snow globe! Since the circuit itself was really quite simple - just a microcontroller, motor driver, and proximity sensor - the now not-so-simple proof of concept project would allow me to do a little bit of 3D design and printing.

Eben Upton interview: Raspberry Pi availability and more #RaspberryPi @ChrisBarnatt @Raspberry_Pi
Eben Upton, CEO of Raspberry Pi, interviewed on December 14 2022. Eben talks about supply pressures, Raspberry Pi availability in 2023, industrial Pi applications, his take on RISC-V, and when we may see a Raspberry Pi 5. You can navigate the video using the chapters in the progress bar.

Color Temperature Tunable, High-CRI LED Lamp
In my last post, I discussed the basic requirements and layout of my lamp – I wanted it to be able to control the color temperature and brightness, and I wanted it to be really bright. I experimented with a single strip, and detailed how the control board would work. If you want to try to build your own, the code/boards are here, although it is not very well documented.

Your Own Santa? Thermal Camera Roundup
With Christmas and other end-of-year celebrations, there are gifts. The problem is that your loved ones don’t really know what to get you. Who can blame them? Do you want an Arduino, a Raspberry Pi, or a Blue Pill? Is that 3D printer on sale better than the one you have? Do you even want a second printer? They don’t know. In the best case, they’ll give you gift cards. But sometimes you just have to buy yourself something nice. [Wired] has a suggestion: a phone-based thermal camera. Which one? They have four suggestions ranging from about $150 to $200.

Arduboy Mini Is A Fresh Take On An 8-bit Favorite
We’ve always been big fans of the Arduboy here at Hackaday. When creator Kevin Bates showed us the original prototype back in 2014, the idea was to use his unique method of mounting components inside routed holes in the PCB to produce an electronic business card that was just 1.6 mm thick. But the Internet quickly took notice of the demos he posted online, and what started as a one-off project led to a wildly successful Kickstarter for a sleek handheld gaming system that used modern components and manufacturing techniques to pay homage to the 8-bit retro systems that came before it.
